QML Keys.onReleased fire when pressing key
Comment
1 / 1
The behavior you described, where the Keys.onReleased
signal fires when you press a key, is unexpected. The onReleased
signal in QML should only be emitted when a key is released, not when it is initially pressed.
To troubleshoot this issue, here are a few suggestions:
Verify the QML code:
- Double-check your QML code to ensure that you are correctly handling the
onReleased
signal. - Make sure that there are no accidental assignments or function calls that may trigger the signal unintentionally.
- Double-check your QML code to ensure that you are correctly handling the
Check for conflicting key event handlers:
- Ensure that there are no other key event handlers or key event listeners in your QML code that might interfere with the desired behavior.
- Review the code to see if there are any other components or event handlers that may be capturing or modifying the key events.
Test with a minimal QML example:
- Create a minimal QML application that only contains the necessary components and the
Keys.onReleased
handler. - Run the minimal application and see if the issue still occurs.
- If the issue persists in the minimal example, it could indicate a problem with the QML engine or the environment you are running the application in.
- Create a minimal QML application that only contains the necessary components and the
Update or reinstall Qt:
- Ensure that you are using the latest version of Qt and the Qt Quick module.
- Check for any updates or bug fixes related to key events or the
Keys.onReleased
signal. - If you suspect a problem with your Qt installation, consider reinstalling Qt or using a different version.
Test on different platforms:
- Try running your QML application on different platforms or operating systems to see if the issue is specific to your current environment.
- If the problem occurs only on a specific platform, it could be related to platform-specific issues or configurations.
If none of the above steps resolve the issue, please provide a minimal and complete example of your QML code so that I can assist you further in identifying the cause of the unexpected behavior.
